Printer can print number of pages in a minute = 15
Printer can print number of pages in a 150 minutes = 15 * 150 = 2250 pages
Or 15*60 minutes=900 * 2.5 times = D is the answer
Not a CAT question in the GMAT or GRE field.

[quote="chrisbarett"]Ohh, hell, I recounted this task three times, but I still could not get the right answer. How did you solve this problem?
15 pages every 60 seconds. 60 seconds every minute. 60 minutes in every hour. and 2.5 hours are asked.
15 pages*60 seconds* 60 minutes* 2.5 hours/60 seconds.
I used the concept of dimensional analysis to convert units from seconds to hours.
Try dimensional analysis to find out how many seconds in a day!
